Design for Energy-Saving Variable Frequency Constant Pressure Water Supply Control System
Abstract
As people living standard rise increasingly, the urban construction, the consumption of enterprise, and increase of water to improve the quality of drinking water problem, thus make city have become increasingly prominent, and how to keep the constant pressure water supply, improve water quality, and also supply reliability and safety requirements, and in response to building the saving-type society, rational development, utilization and save energy, save the effective protection of water resources has become an arduous task.
Analysis and check the task of urban water supply system, has the following characteristics. The water users, mostly in time to wake up in the morning, afternoon session, which USES the home is also great transformation of water supply system, and the high cost of existence, the reliability of the water resources, low waste is serious, imperfect network system.
This paper describes using PLC control to achieve energy-saving control system for constant pressure water supply inverter design. This design introduces a frequency control constant pressure water supply system, which can be instantaneous pressure changes under the pipe network, automatically adjust the speed of a water pump station pumps and multi-input and exit, so that the outlet end of the trunk pipeline network to maintain a constant set pressure value, and to meet the needs of the user's traffic, so that the whole system has to maintain energy-efficient best. Under the constant pressure water supply system control requirements, modules and implementing agencies (pump) for selection. In the analysis and comparison of several programs are given on the basis of the design implementation of the program. Finally, the software debugging process of the problems encountered and solutions are described.
